Couldn't we stick it in again later to try again? If we sacrifice the rat and the USB stick stays in there, the whole situation could be compromised because the person would notice there's a USB stick doing something in there that wasn't there before. Not to mention, the rat with bloody bandages would be incredibly suspicious, considering what they've seen of our bloody-bandaged nurse and her bloody-bandage powers through the camera livestream from the hospital. Security could ratchet up. >_> I dunno, man...

Does the door to the security office have a lock? We could lock it, maybe delay the person coming in for another little bit while they get out their keys...

Otherwise, taking out the USB stick and trying again once the person leaves (as long as that won't mess the program up or something, or leave visible evidence that we were trying to do something) might be the best choice.

As much as my instincts tell me this is a bad idea in the long run I'm going to have to say we gotta take it out and scurry our rat self back into the vent. We can atleast listen and observe at that point.
